Resumo: In this paper, poly(acrylamide-co-dialidimethylamonium)-PAADDA films containing lithium sulfate (Li2SO4) were prepared by casting method from aqueous solutions. The obtained films (pristine PAADDA, PAADDA/Li2SO4-0.25% w/w, and PAADDA/Li2SO4-0.5% w/w) were characterized by means of attenuated total reflectance-Fourier transform infrared spectroscopy (ATR-FTIR), thermogravimetric analysis (TGA), and electrochemical impedance spectroscopy (EIS). ATR-FTIR spectra of PAADDA/Li2SO4 films showed the main bands of PAADDA and suggested a significative intermolecular interaction between the polymer and Li2SO4. TGA curves displayed that the thermal stability of PAADDA film is dependent on the Li2SO4 concentration. The ionic conductivity of the films followed the order: PAADDA/Li2SO4-0.25% w/w < pristine PAADDA <PAADDA/Li2SO4-0.5% w/w.

Os filmes obtidos (PAADDA, PAADDA/Li2SO4-0,25% m/m e PAADDA/Li2SO4-0,5% m/m) foram caracterizados por espectroscopia de infravermelho por transformada de Fourier com refletância total atenuada (ATR-FTIR), análise termogravimétrica (TGA) e espectroscopia de impedância eletroquímica (EIE). Os espectros ATR-FTIR dos filmes de PAADDA/Li2SO4 mostraram as principais bandas do PAADDA e sugeriram uma interação intermolecular significativa entre o polímero e o Li2SO4. As curvas TGA mostraram que a estabilidade térmica do filme de PAADDA é dependente da concentração do Li2SO4. A condutividade iônica dos filmes seguiu a ordem: PAADDA/Li2SO4-0.25% w/w < PAADDA < PAADDA/Li2SO4-0.5% w/w.Universidade Federal de Viçosa - UFV2023-09-21info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufv.br/jcec/article/view/1645310.18540/jcecvl9iss8pp16453-01eThe Journal of Engineering and Exact Sciences; Vol. 9 No. 8 (2023); 16453-01eThe Journal of Engineering and Exact Sciences; Vol. 9 Núm. 8 (2023); 16453-01eThe Journal of Engineering and Exact Sciences; v. 9 n. 8 (2023); 16453-01e2527-1075reponame:Revista de Engenharia Química e Químicainstname:Universidade Federal de Viçosa (UFV)instacron:UFVenghttps://periodicos.ufv.br/jcec/article/view/16453/8248Copyright (c) 2023 The Journal of Engineering and Exact Scienceshttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessCaetano, Ian Pellinca BragaMelo, Rodrigo de Siqueira Freitas, Kênia da SilvaShiguihara, Ana LuciaAmim Júnior, Jorge2023-11-09T11:24:16Zoai:ojs.periodicos.ufv.br:article/16453Revistahttp://www.seer.ufv.br/seer/rbeq2/index.php/req2/indexONGhttps://periodicos.ufv.br/jcec/oaijcec.journal@ufv.br||req2@ufv.br2446-94162446-9416opendoar:2023-11-09T11:24:16Revista de Engenharia Química e Química - Universidade Federal de Viçosa (UFV)false
